Horsewood's label is refreshingly transparent: seven active ingredients, each with its own amount, no proprietary blend and no stimulants. It is built around Tongkat Ali, one of the best-studied botanicals in men's vitality, supported by traditional herbs and a trace mineral. Read the extract ratios correctly, follow the 60-capsule label rather than the contact page, and you will know exactly what you are taking.
What we like
- Every ingredient listed with an individual amount
- Led by Tongkat Ali, the most researched herb in the category
- No stimulants and a short list of other ingredients
- Label revision and origin ("Assembled in the USA") printed on the panel
Keep in mind
- Several supporting herbs have little human research behind them
- Extract ratios can be confusing if you are used to raw-powder labels
- The contact page FAQ contradicts the label on capsule count

The fastest way to understand Horsewood is to skip the "horse gelatin trick" videos entirely and look at the Supplement Facts panel. It is the one document the brand has to get right, and it answers most of the questions people search for: what is in it, how much, and how many capsules to take. This is the panel shown on the official website, label revision 11/25:
What does the Horsewood label actually list?
Reading from the top of the panel down, here is how it is organized:
| Line on the label | What it says |
|---|---|
| Serving size | 2 capsules |
| Servings per container | 30 (60 capsules per bottle) |
| Headline botanical | Tongkat Ali, 10 mg of a 100:1 extract |
| Second botanical | Horny Goat Weed (Epimedium sagittatum), 8 mg of a 10:1 extract |
| Supporting botanicals, 20 mg each | Saw palmetto, wild yam, sarsaparilla (Smilax ornata), nettle leaf |
| Mineral | Boron (amino acid chelate), 20 mg |
| Other ingredients | Microcrystalline cellulose, gelatin, magnesium stearate |
| Origin | "Assembled in the USA" |
Two details are worth pausing on. First, there is no proprietary blend: each active ingredient has its own number, so you are not left guessing how much of the formula is filler. Second, the panel says "Assembled in the USA", which is the phrase the brand chose. It means the product is put together in the United States; it is a different wording from "Made in the USA", and the label does not say where each raw botanical is grown.
What "equivalent to 1,000 mg" means on the Horsewood label
Many pages describe Horsewood as having "1,000 mg of Tongkat Ali". The label is more precise, and it helps to see how it works.
Herbal extracts are often labeled by ratio. A 100:1 extract means roughly 100 parts of dried root were processed down to 1 part of finished extract. So the label lists 10 mg of extract and describes that as equivalent to about 1,000 mg of dried root. The same logic applies to Horny Goat Weed: 8 mg of a 10:1 extract, described as about 80 mg.
A kitchen comparison makes it concrete: a spoonful of tomato paste starts as several tomatoes. Both descriptions are true; they just measure different things. When you compare Horsewood with other products, compare extract to extract and dried root to dried root, and read the ratio rather than the biggest number on the page.
Is it 30 capsules or 60? The contact-page mistake
This is the Horsewood confusion we see most often. The FAQ on the brand's contact page says a bottle has 30 capsules and that you take one a day. The Supplement Facts label and the sales page both say 60 capsules, two per serving.
The label wins. Every ingredient amount on the panel is calculated per two-capsule serving, so taking one capsule would give you half of each listed amount, and a bottle would last two months instead of one. If you have read the one-a-day figure somewhere, it most likely traces back to that contact page, and it does not match the bottle.

Horsewood's two headline ingredients
Most of the formula's identity comes from these two botanicals, both used in traditional practice for centuries before they appeared in capsules.
Tongkat Ali
10 mg of 100:1 extractA root from Southeast Asia used for generations as a traditional tonic for male vitality, and one of the better-studied herbs in this category: a 2022 meta-analysis of randomized controlled trials found that Tongkat Ali raised total testosterone, most clearly in men who started with low levels. The 100:1 concentration is why the label describes 10 mg as equivalent to about 1,000 mg of dried root.
Horny Goat Weed (Epimedium)
8 mg of 10:1 extractA herb with a long history in traditional Chinese practice. Its best-known compound, icariin, has been studied in the laboratory for its effect on the enzyme pathway involved in blood flow. Human research is still early, so think of it as a traditional ingredient with interesting lab data.
Where Tongkat Ali comes from
Tongkat Ali (Eurycoma longifolia) is a slender tree native to the rainforests of Malaysia, Indonesia and neighboring countries. It is the root that is used, and it is famously bitter, which is one reason it is sold as a concentrated extract in capsules rather than as a tea. It is also the ingredient with the most human research of anything on the Horsewood label, mostly focused on men's hormone levels. That research is about the herb in general, not about Horsewood as a finished product.
Where Horny Goat Weed comes from
Epimedium is a low-growing leafy plant from China and East Asia, known in traditional Chinese practice for centuries. The English name comes from a folk story about goats grazing on it. Horsewood specifies the species, Epimedium sagittatum, which is a sign the label was written with care. Most of the modern research on its compound icariin comes from laboratory and animal studies.
The supporting cast
The remaining five ingredients are each listed at 20 mg. They round out the formula with herbs and a mineral that appear across many men's wellness products.
Saw Palmetto
20 mgOne of the most popular botanicals in men's health, known mainly for supporting prostate and urinary comfort as men age. Clinical results have been mixed, but it remains a staple of men's formulas.
Nettle Leaf
20 mgStinging nettle has been used in traditional herbal practice for centuries and is a common ingredient in men's wellness blends. Modern clinical evidence for the leaf is limited, so it plays a supporting role here.
Wild Yam Root
20 mgA classic herbal ingredient, traditionally used in wellness blends for both men and women. It contains diosgenin, a plant compound; research in people is limited, so we treat it as a supporting ingredient.
Sarsaparilla Root
20 mgA tropical vine root with a long record of traditional use as a tonic, and the original flavor behind the old-fashioned soft drink. It is included for its traditional use rather than strong clinical data.
Boron
20 mg (amino acid chelate)A trace mineral found naturally in nuts, fruits and vegetables. Small studies have looked at how boron intake relates to hormone levels in men, which is why it appears in many vitality formulas.
Saw palmetto: a Florida native
Saw palmetto is a small palm that grows wild across the southeastern United States, especially Florida. Its berries were a traditional food and remedy long before they became one of the best-selling men's botanicals in the country. Research has centered on prostate and urinary comfort, with mixed results according to the NIH's NCCIH.
Nettle leaf, not nettle root
The label specifies nettle leaf. That matters because nettle root and nettle leaf are studied for different things, and product pages often mix them up. Leaf is the traditional part used in herbal teas and tonics; modern clinical evidence for it is limited.
Wild yam and the "natural DHEA" myth
Wild yam root contains diosgenin, a plant compound that laboratories can use as a starting material for making hormones. The human body cannot do that conversion, so wild yam does not turn into DHEA once you swallow it. It is included for its traditional use.
Why Horsewood's sarsaparilla is different: Smilax ornata
This is the single line that sets Horsewood's label apart from its near-twin, Vigortrix. Both formulas list sarsaparilla root at 20 mg, but Horsewood specifies Smilax ornata, a species from Central America often called Jamaican sarsaparilla, while Vigortrix lists Smilax glabra, an Asian species. Both are traditional tonic roots, and neither has much human research, but if you want the exact species, it is printed on the panel. Our Vigortrix vs Horsewood comparison puts both labels side by side.
Boron as an amino acid chelate
Boron is a trace mineral we all get from fruit, nuts and vegetables. "Amino acid chelate" describes the form: the mineral is bound to an amino acid, a common way of presenting minerals in supplements. Small studies have explored boron and hormone levels in men, which is why it appears in many vitality formulas.
What is not in Horsewood
- No horse ingredient. Despite the marketing, nothing horse-derived is listed as an active ingredient. The capsule shell is standard gelatin.
- No stimulants. The label lists no caffeine, yohimbe or similar ingredients.
- No proprietary blend. Every active ingredient has its own amount.
If you find a page describing Horsewood with a different ingredient list, check which website it is on. Copycat domains such as horsewood-usa.us or horse-woods.us are not the brand, and the bottle label is the only list that counts.

Who should check the ingredients with a doctor
The label says not to exceed the recommended dose, not for anyone under 18, not for pregnant or nursing women, and to consult a physician if you have a medical condition. Based on the ingredients, we would add: ask your doctor first if you take nitrates, blood pressure medication, ED prescriptions or blood thinners (saw palmetto may interact with anticoagulants, per the NCCIH), and show them the label if you already take a multivitamin with boron.
